1. Please don\'t use Makita DC18RA DC18RB DC18RC DC18SD Rapid Battery Charger to charge TMK058 (except TMK062). The high current charging will damage the battery.
2. Most of original power tool battery packs would not have individual cell voltage monitoring system inside. When any of cells inside the pack is being over-charged, charger will not stop charging and thus incur risk of explosion. To ensure safety operation, a cell voltage monitoring mechanism is added to circuitry in our power tool battery packs. When protection IC detects any of cells in the pack is being over-charged, it will generate a signal to cut off NTC and stop charger from continuing charging the battery pack, therefore avoiding the risk of explosion.
